What you’ll play

Pick your fight.

Memory, speed, or seeing what’s hidden — each game takes seconds to understand and gives you back a fight exactly your size. No reading, no tutorial, no warm-up. Two are playable right here.

Memory Grid

How much can you hold in your head?

A pattern lights up, then vanishes — and for a few seconds it exists nowhere but in your head. Put it back exactly, and next time you’ll be trusted with more.

Box Count

Count what you can’t see.

A stack of cubes flashes and disappears, and some of them were hidden behind the others the whole time. Your eyes got half the answer. The rest is yours to work out.

Memory

Number Memory

Nine digits. Think you can hold them?

Three digits is nothing. But somewhere past your comfort zone there’s a number that slips as you reach for it — and finding out where that line is, then moving it, is the game.

Speed

Reaction Tap

How fast are you, really?

Not “pretty fast.” A number, in milliseconds, of the gap between your eyes and your hand. Jump early and it doesn’t count — this rewards nerve as much as speed.

Speed

Stop the Clock

Land it on the exact hundredth.

The clock is right there in front of you, counting up in plain sight — and you’ll still miss by a fraction. The players who master this one aren’t the fast ones. They’re the calm ones.
